Application January 6, 19`2i2. S'erial No. 527,502.

To all whom t may concern@ Be it known that We, FRANK M ARK and HoMER ,L McCoNooitY, both citizens of the United States, residing in the city of Portland, in the lcounty of Jay, `State of Indiana, have jointly invented anew and useful ElectricFiiel Vaporizer, O` which the followingwis a fullyc ear, `,and comprehensive specification and expfosition, the samev being such as will enable thers to make and use the-same with eX titude. l The y object Wo', our present,` invention, broadly speakinAv is to proyide an electric fuel-vaporizer gflor internal combustion motors, the saine beingof simple. construction, adapted to be and quicklyinstalled in connection withthe -'fuel system, thesame being inexpensive in` maintenance, easil operated and controlled,and which can he manufactured andsold at a comparativelylowprice. Thespecliie object .of this invention is to provide an economical and highly efficient means for quickly yaporizing liquid fuel as the `tuel passes from the carbureter vinto the manifold, the samebeing especially applicable when .the .motoryandtthe other parts, arecold thereby enabling one to start a very coldmotor as easily as it would be if the .motor was hot.` y y,

Other minor objects and; particularadvant-ages ofthe invention will Vsu vgest them selves in the cour,'.=i e .,of the following de scription and that`4 which ishnew will `be correlated inthe appended claims. Thepreferred means for carrying out th objects of our vinvention in a practical and mechanically eiiicient manner isshown in the yaccompan ing drawings, in whichf Figure l s ows in, elevation the upper yportion of a carbureter and .thelower portion of `an intake manifold, showing vour invention as installed inoperative condition therebetween, and also showing the electrical connections of the invention.

Figure 2 showsa plan view of the body portion of the device, showingcertain portions as broken away to more clearly show the construction. ,And Figure 3 is a central Icr s section of the main portion or body of t e invention, as taken on the line 3 3 of Fig. 2. I Similar indcesdpnote like parts throughout the several views.

In order that the construction, the operation, and the advantages of the invention may be more fully understood and appreciated, we will now take up a detail description thereon'in which we will set forth theinvention as fully and as clearly as we ma eferringI now to the drawings in detail:

Letter A denotes -the. upperend or ange of y a carburetor. B denotes the vlower Harige of the intake manifold D, vthe flanges A and B being identical with each other, and they are ordinarily contacted with each other, or with a gasket therebetween, and they are adapted to be tightly clamped and secured together by the screws or bolts C+C.

,y Our invention comprises a .bodyl whose outlinelshape corresponds .with the shape of the flanges A and B, and having bolt notches 2 and tformed in .its end portions to register wi h the bolt apertures in the flanges A andB,

A centralaperture 4 is formed through the body 1 audit corresponds in size with the passageways in the upper portion of the carburetor and the lower portion of the manifold., Located in lthe centerv of the aperture 4 a disc 5. in the center of which is an aperture 6. The disc 5 is integrally connected with the body 1 by the rarms 7 and S. Said. disc andthe arms 7 and 8 are'l of less thickness .than the body 1, and

they are located in line with the lower face y thereof, substantially as shown in Fig. 3. Also extendimqr into the aperture 4, from the body 1, are the two oppositely disposed Wings 9 and 10. Said wings are of the same thickness as are the disc 5 and the arms 7 and 8, and they are located on a level therewith, as in Fig. A. plurality of small apertures E are formed through the disc 5,

the arms 7 8, andv the `wings and 10,

l'stance therefrom. is a channel 12 in which 1s located the endless resistance coil 13.

Said coil is packed in a special cement by which the coil is insulated from the metal of the body l, and when said cement solidiies it iiorms not only an insulator but acts as a radiator element lfor the heat which is generated in the coil. y

At one point the coil 13 is grounded to the body 1 by means of a screw 14, or other means. Directly opposite to the screw 1d a a wire 15 is connected to the coil 13 and it extends outward therefrom through an aperture formed therefor in the body l. f

Numerals 18 and 17 denote gaskets, each corresponding in outline with the peripheral shape ci' the body 1, and with the central portion ot said gaskets cut-away to i'orm apertures therethrough of a size equal to the size oi' the central apertures.

The body portion of the device is placed in position as follows: rEhe bolts C-C are first remoyed, allowing` the flanges A and B to be spaced apart, after which the body l, together with the gaskets 16 and 17 on each side thereoi, are then placed between the langes A and B, after which the bolts C-C are again inserted, this time passing` through the apertures 2 and 3 and the similar apertures of the gaskets, andlas said bolts are tightened the body l will be clamped in operative position as is shown in Fig. 1. i i

Numeral 18 denotes an electric switch, oi ordinary construction, having a push button 19 in connection therewith. Said switch should be secured to the linstrument board and within reach oi the driver ot the automobile with which it is connected. The wire 15 is extended to and is secured to one pole of the switch, as sho-wn. A wire 20 is eX- tendedfrom the other pole of the switch to one pole of the ammeterX located on the instrument board, thereby completing` the electrical connection with the storage battery and with our vapori/ser or sub-carburetor. i

It is now evident that if the switch be closed that an electric current will flow 'from the battery, through the wires 2O and 15, to the coil 13, the return current being through the ground 111, thereby causingthe coil to heat and by which the adjacent parts, particularly the inner wall of the body 1,`the arms 7 and 8, the disc 5, and the wings 9 and 10, will be heated whereby the gas or gasoline which. passes through the central aperture of the body l will be heated whereby it becomes volatile and highly explosive before it enters the manifold l).

Therefore it is apparent that by the employment of our invention the fuel passing;d into the tiring),` chambers of the motor will be easily exploded, thereby making the starting oit the motor as easyin cold weather as when the atmosphere is warm.

ln practice the first thing to do when one desires to start his cold motor is to close the switch 18 to establish the electric circuit, and allow a short time, one ortwo minutes, for the coil to heat up the adjacent parts. vThe motor may then be started in the usual manner but permitting,r the switch `to remain closed until the motor is thoroughly warmed, after which the switch may be.

opened to cut oli3 the current from the coil.

lt is to be understood that our body member l not limited to the position as shown, as in some cases it may be best to employ it the other side up from that shown, that is with the screen 11 below the disc 5, ln fact the screen 11 may be entirely dispensed with in some instances.

lVe also desire that it be understood that various other changes may be made in the several details of construction shown without departing 'from the spirit of the invention and `without sacricing any ofthe adv vantages thereof which are new and useful.

Having now fully shown and described our invention, what we claim and desire to securey by Letters Patent of the United States, is-

l. A luel-vaporizer comprising a flat body having1 a central aperture therethrough, an electric heater located in a channel formed in one face ofthe body and concentric of the central aperture, means iforconducting the fiange of a manifold and the flange of a carburetor, gaskets spacing said body from said lianpes,y an electric heat producing means extending entirely around said aperture in the vbody and located entirely in a channel formed in one face of the body, an electric conductor extending through the edgeof the body to the heat producing means, and a grounding means connected to said heat producing means, all substantially as shown and described.

An electric Vfuel vaporizer comprising, in combination, a bodymember adapted to be secured between a' carburetor and a manil-old of an explosive motor, an endless resistance coil imbedded in said body concentric of the passage-way therethrough, means tor insulating said coil from the body,
